Dyson Launches $750 Smart Toothbrush with AI Technology

The new toothbrush autonomously sprays water between teeth. When the brush head is moved against the teeth, a built-in camera identifies the gaps and sprays liquid toward them within 0.1 seconds. This device combines the functions of brushing and flossing into one product.

The 'Dyson Camera Jet,' Dyson's first oral care product developed over six years, was introduced at a press conference on September 10 at Banpo Hangang Park in Seoul. Rich Bacon, head of Dyson's new business division, explained the product's core technology and operation, highlighting the integration of vision systems, artificial intelligence (AI), and precision fluid dynamics.

"Dyson has focused on addressing everyday inconveniences faced by consumers rather than limiting itself to specific business areas," Bacon said. "We have long recognized the importance of inter-dental cleaning and have been dedicated to developing related technologies."

He added, "Our goal is to present a more convenient oral care method by integrating brushing and inter-dental cleaning into a single process. The Dyson Camera Jet embodies various engineering technologies, including vision systems, machine learning, and precision fluid dynamics that Dyson has developed over time."


Dyson's focus on oral care follows its success in vacuum cleaners and hair care products, driven by the need for effective inter-dental cleaning. Bacon noted, "Oral care has remained a repetitive process for decades, involving squeezing toothpaste, brushing, rinsing, and using floss. Many people understand the importance of flossing but find it tedious and time-consuming, leading to low compliance with recommendations."

In South Korea, a 2026 survey by Korea Research found that while 77% of 1,000 adult respondents reported using floss or inter-dental brushes, only 28% did so regularly. Dyson observed that although South Korea has better access to preventive dental care and a well-established brushing culture, the use of floss and inter-dental brushes has not yet become a regular habit.

To address this, Dyson developed a key technology called 'Gap Optical Targeting.' This AI machine learning algorithm was trained on 470,000 images of teeth. A 1mm², 100,000-pixel macro camera analyzes 28 images per second to predict gaps between teeth. Once a gap is detected, liquid is sprayed in a cone shape toward the target within 0.1 seconds.

Identifying inter-dental spaces accurately while the vibrating toothbrush is in motion posed a significant challenge. Bacon likened it to taking a photo while shaking a smartphone. He explained that the AI algorithm was trained on approximately 500,000 images and that the product contains about 16 million lines of software code. The toothbrush captures images while in motion, combining them to ensure stable video and identify inter-dental spaces.

The precise liquid spray is made possible by Dyson's accumulated fluid dynamics technology. Instead of indiscriminately spraying water upon detecting a gap, the device assesses the tooth surface and sprays at the appropriate moment. The liquid is designed to spread in a cone shape, covering the surface between teeth while minimizing pressure on the gums and teeth.

Dyson's motor technology is also applied to the toothbrush's cleaning function. The sonic motor driving the three-dimensional sonic brush vibrates 245 times per second. The dual-bristle head is designed to adapt to the contours of uneven teeth, with stiffer bristles in the center and softer bristles on the outer edges to manage the tooth surface and gum line effectively.


The event was designed to allow attendees to experience the Camera Jet's operation firsthand. Upon passing through an entrance shaped like a cone jet spray, participants could see a media art display capturing the camera's ability to identify gaps between teeth. There were also tech zones to explore the product development process and demo zones to try the Camera Jet.

In the demo zone, using the actual product, brushing began as the brush head was moved against the teeth, with water automatically spraying each time the camera recognized a gap. A manual mode is also available, allowing users to spray liquid at their discretion.

Using a smartphone, users can view their oral cavity in real time. The 'Live View' feature of the MyDyson app allows users to see the inside of their mouth as captured by the toothbrush's camera. The app also provides data on brushing time and habits to help users develop proper brushing practices.

Bacon stated, "You can see the same view that a dentist would see while brushing." The camera activates only when using the live view or automatic jet spray functions, and captured images are not stored on the device or in the cloud.

Currently, there are no dedicated cleaning solutions or toothpaste for the Camera Jet available in South Korea. To use the device, users must fill the tank with water for inter-dental cleaning and apply regular toothpaste to the brush head.

The Camera Jet is priced at 749,000 won in South Korea, including the main unit, two dual-bristle heads, a refill dock, and a USB-C cable.
